SPECIFICATION forming part of Letters Patent No. 230,161, dated July 20,1880.

Application filed May 28, 1880.

(No model) To all whom it may concern:

Be it known that I, WILLIAM I. WALKER, a citizen of the United States,residing at Macon, in the county of Macon and State of Missouri, haveinvented certain new and useful Improvements in Tin or Metal Roofing;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being bad to the annexed drawings,making a part of this specification, and to the letters and figures ofreference marked thereon.

Figure l is a perspective view of my invention. Fig. 2 is a longitudinalsection of the same. Fig. 3 is a plan View of the sheet-metal blank fromwhich the end cap is formed, and Fig 4 is a perspective view of the capbent into form ready for securing in place upon the roof.

This invention has relation to certain new and useful improvements insheet-metal roofing; and the object thereof is to so cover the roof withsheet metal as to render it perfectly wind and water tight, and at thesame time render the roofing firm and lasting, so that there will be nodanger of the metal sheeting working loose and rattling, caused by thewind getting under it.

The invention consists in the peculiar manner of laying and securing themetal sheets and manner of constructingthe end caps which are placedover the strips of wood, as shown in the drawings and hereinafterdescribed.

In the accompanying drawings, A represents a section of a roof, to whichare secured the wooden strips B, a strip of sheet metal, 0, being firstlaid upon the roof and turned up so as to come in between the mortar andbrick,

of the wall when there is one upon the roof, the purpose being toprevent leaks. The wooden strips are then secured to the roof, beginningwith the first one, the metal plate D at the left of the strip beingturned up against the side thereof and secured by nailing, the metalplate at the right of the strip being similarly secured in place and tothe wooden strip, as shown at X, Fig. 2. The wooden strips andsheet-metal plates are thus connected to the roof and togetherthroughout the width of said roof, after which flanged caps E F areslipped over the flanges a of the plates D, and afterward bent downagainst the sides of the wooden strips, as shown, respectively, in Y Z,Fig. 2, the rear ends of the plates D and caps E being secured by solderto the sheet-metal strip G, which prevents wind or dampness from gettingin and rusting the sheet metal. Where these wooden strips B are used itis essential, to successfully complete the roofing and preserve thestrips from the dampness, to have them thoroughly covered and protectedat their ends. This I accomplish by forming the caps F with an apron,Gr, having ears or flaps b, said cap with its apron and flaps beingstamped in the form shown in Fig. 3, after which it is bent in the formshown in Fig. 4.

After the caps E F have been secured in place upon the top of the woodenstrips B the aprons G of the caps F are nicely fitted around the endsofsaid strips and nailed thereto, the flaps I) being pressed or hammeredagainst the sides of the wooden strips and soldered to the plates D,thus forming a perfect and durable shield for the. ends of the woodenstrips.

The caps E are formed with single flanges 0, while the caps F havedouble flanges d, these flanges being formed by suitable machinery readyto be applied to the roof.

The plates D being secured to the roof and to the wooden strips, asillustrated at X, Fig. 2, the edges are turned out at right angles, asshown in dotted lines, after which the caps E are placed over them andnext the caps F.

The advantage of having the caps F formed with the double flanges d isthat they can be slid along over the flanges of the plates D, and aresecurely held in place thereon while they are being bent down, as shownat Z, Fig. 2, and the aprons G secured by soldering to the plates, thecaps F being completed by suitable machinery, ready to be applied to theroof, as shown in Fig. 4: of the drawings.

The manner of laying the sheet-metal plates to the roof and to thewooden strips, in connection with the flanged caps, makes a very strongand durable roofing-one that will not easily become injured by heat orcold or by severe storms, and as the metal plates and caps are firmlyconnected together there is no danger of the plates or caps workingloose and a very essential feature of my invention is the
